BROOM CONSTRUCTION Filed March- 13. 1929 Patented July 14, 1931 UNITED STATES CHARLES LEO WINGARD, OF PORTLAND, OREGON BROOM CONSTRUCTION Application filed March 13, 1829. Serial No. 346,616.

My new and improved construction consists primarily of a broom head holder made of sheet material and preferably made of two pieces secured together at oppositely disposed edges and terminating in the handle structure having a handle removably secured to the head.

The primary purpose and object of my new and improved construction resides in a fabricated head arranged to maintain the straw or fiber sweeping material within the head by being clamped between the head members without the aid of wire or other clamping material being used extraneous of the head members.

. At the present time in broom construction, the sweeping portion of the broom is made integral with the handle so that when the sweeping portion of the broom has been 2 worn away the handle becomes useless.

In my new and improved construction, the handle is removably secured to the head so that one handle may be made to serve any number of sweeping heads.

A further object of my new and improved construction resides in the fact that the handle is removably secured to the head and is made independent of the sweeping head so that the broom heads may be shipped or delivered as a sweeping head thus effecting a very great saving in transportation and packing charges.

A further object of my new and improved construction resides in a structure that clamps the straw or fiber within a head with a minimum of labor and time required.

And still further objects of my invention consist in placing an ear hingedly disposed at one side of the assembled head that may 0 be used in supporting the sweeping head or that may be used as a support for a dust pan and the like.

With these and incidental objects in view, the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which is hereinafter shown with reference to the drawings which accompany and form a part of this specification.

In the drawings:

Fig. 1 is a side view of a broom, illustrating the handle in position therein.

Fig. 2 is a side view of the handle and broom head, illustrating the handle re-- moved from the sweeping head.

Fig. 3 IS a cross section view of the sweeping head, taken on line 33 of Fig. 2, look ing in the direction indicated.

Fig. i is a sectional, front view of the sweeping head.

Fig. 5 is a side view of the sweeping head,

core into which the handle may be removably secured.

Fig. 7 in preferred embodiment is a front view, partially in section of the sweeping head, illustrating the handle attaching core partially in section disposed within the head.

Fig. 8 is a top, plan view, partially in section, made on line 8-8 of Fig. 7 looking in the direction indicated.

Fig. 9 is a detail view of the lapping edges.

Like reference characters refer to like parts throughout the several views.

I-Ieretofore it has been the general custom to make the sweeping head and handle integral with each other so that upon the disintegration of the sweeping head the handle became useless.

In my new and improved device, I prefer ably make the sweeping head of two side wall members 1 and 2, preferably made of sheet stock and lapping their oppositely di posed edges as illustrated in Fig. 9 at 3 and 4, and secured the same by pressure together after engagement has been effected which may afterwards be sealed by welding or soldering. The fiber material 5, being placed between the side wall members comprising the head and the clamping of the side wall members compressing the head, clamps the fiber therebetween. Transversely disposed ribs 6 and 7 are disposed at either side and adjacent the lower end of the side wall members to stiffen the same. Locking threads 9 are formed within the shank 1O portion of the side walls into which the handle member 11 may be made to engage. The threads 9 are preferably made of the interlocking L-shaped type of thread having its inner leg form integral with the. shank portion 10, and havmg an outwardly extending leg that forms a recess so that the thread keeps the shank portion from spreading action and at the same time locks the handle from removal. The handle preferably having upon its outer surface a threaded ferrule 12 disposed on its lower end comprising of interlocking L shaped threads in registerable alignment with interlocking threads 9 for threaded engagement with the shank portion 10 of the head member.

A modified and preferred form of construction is as illustrated in Figs. 6 and 7 wherein the handle engaging central core 13, as illustrated in Fig. 6, is secured within and locked to the side wall members 1 and 2 the centralcore 13 having the locking thread 14: disposed its inner surface into which the handle 11 haying. ferrule 12 may be secured by threaded engagement.

Heretofore it has been the general custom to make broom handles of relatively cheap material, but by the construction herewith illustrated, the handle member may be made of long lived, or, relatively permanent material and as the sweeping head. becomes worn,the handle may be removedtherefnom and placed within a new sweeping head thereby lessening the cost of the handle being supplied with each sweeping head,

lessening the cost of the transportation of the handle and at the sametime making. the handle interchangeable with a number'of sweeping heads. The handle element may also be used for mops, dust brooms, as well as that of the broom structure. It is also found desirable in the construction to form a ledge 17 inwardly extending, from. the lower peripheral edge 18 of the side wall members in order that; the same maybe made to more efficiently clamp the. fiber forming the broom.

I form a support 8 from one of. the side wall members of the sweeping, head and from a hole 8A. therein for supporting. the sweeping. head and also form an upwardly extending hook 8B over which. the bail of a dust pan may be supported.

lVhile the form of mechanism herein shown and described is admirably-adaptedto fulfill the objects primarily stated it is to be, understood, that it is not intended to. confine the invention to the one form of embodiment herein shown and described, as it is susceptible. of embodiment in various forms, all coming within the scope of the claims which follow.

What I claim is:

1. In a device of the class described, in combination with a broom head, a core disposed within the broom head, said core having an interlocking L shaped thread disposed upon itsin-ner surface, and a handle having an interlocking L shaped thread disposed: about its lower end, said thread being in directthreaded alignment with-the interlocking thread within the core, and being adapted for preventing transverse andlongitudinal strain on the connecting parts when the broom is used.

2. In a device of the class described the combination of a broom head and a broom handle, said. broom head comprising side wall members clamped together, a core disposed within the broom head, said core having L-shaped threads therein, and a handle detachably attachable to the broom head, said handle having an Lshaped ferrule at its engaging end adapted'to interlock with the threads disposed withinthecore.

3. In a device of the class described, in combination, a core, an, interlocking l -shaped thread disposed within the core, a sweeping broom head disposed about the core andv fixedly secured thereto, and a handle detachably attachable within the core, said handle having an interlockingL-shaped thread disposed about its engaging end and adapted to intimately coact. with the L -shaped threads disposed within thecore when the handle is attachedto the core.

4. A broom head comprising a pairof side wall members, saidmembers secured" to gether at their sides by interlocking fnrca;

tions, an inwardly extending ledge disposed at their peripheral edge, and a core securely positioned within the broom head between the wall members, said core having an; interlocking L-shaped thread disposed upon its inner surface.
